 ## 0.1.0 (Pending)
 
  * Add support for Unicode variant encodings, used by MacOSX 10.9 / iOS 7.
    - For more info: http://www.unicode.org/L2/L2011/11438-emoji-var.pdf
    - By default, `EmojiChar.to_s()` and `.char()` will now use the variant encoding.
+ * With adding support for variants, the speed of `find_by_str` regressed by approximately 20% (because there are more codepoints to match against). To counter this, we switched to a Regex based scan than improves performance of the method by over 250x(!).  A complete sorted search against 1000 strings now takes ~2ms where before it would take around a half second.
  * Import latest version of iamcal/emoji-data.
  * 100% test coverage. :sunglasses:
